Does Zylam Liquid Systemic Insecticide address pine bark beetles? If so, would it stop further stem deterioration from trees already hit?

Answer:

Zylam Liquid Systemic Insecticide is not labelled for bark beetles so we would not recommend it. Bark beetles are hard to control once they have infested trees, unfortunately. We suggest spraying the trunk and low branches of susceptible trees with an insecticide such as Permethrin SFR as a preventative treatment. For any trees that may be infested, you should trim infested branches and burn them or bag them for disposal.
